Un passage de tuyauterie (307e) pour mesurer la pression hydraulique dans le passage d'huile hydraulique (210a) et un passage de tuyauterie (307f) pour mesurer la pression hydraulique dans le passage d'huile lubrifiante sont reliés à une plaque de distribution de pression source (51). La plaque de distribution de pression source (51) est disposée sensiblement au centre sur une surface de montage de dispositif hydraulique (10) disposée sur le démultiplicateur à changement de marche marin (1). Le sélecteur marche avant-marche arrière (206) et un moyen de mesure de pression hydraulique comportant des capteurs de pression (52a, 52b…) sont disposés autour de la plaque de distribution de pression source (51). De plus, un arbre d'entrée (2) est disposé en parallèle entre un premier arbre de sortie de prise de mouvement (10) et un arbre intermédiaire (6). Un second arbre de sortie de prise de mouvement (5) est disposé parallèlement à une section côté externe d'un arbre intermédiaire (6) d'un carter (7). Un générateur d'électricité auxiliaire (504) pour faible courant électrique est relié au second arbre de sortie de prise de force (5).
